Frequently Asked Questions
Q: How do I know if this 2-7/16" ID filter will fit my carburetor?
A: This filter is designed for standard karting carburetors with a 2-7/16" outer diameter intake. Always measure your carburetor's intake neck before purchasing to ensure a secure, airtight fit.
Q: How often should I clean my Uni Filter?
A: For optimal performance, especially on dirt tracks, inspect your filter after every race day. If you notice dust or grit buildup, wash it gently with mild soap and water, let it air dry completely, and re-oil if necessary before your next session.
Q: Why choose a straight filter over an angled one?
A: Straight filters like the AFR80 are ideal for chassis setups where space is limited or where the carburetor intake is positioned to allow for a direct, unobstructed airflow path. They help minimize intake drag for consistent throttle response.
Q: Can I use a pre-filter with this air filter?
A: Yes, using a foam pre-filter is highly recommended for dirt track racing. It acts as a first line of defense against larger debris, extending the life of your main fabric filter and keeping your engine breathing clean air longer.
